What is Insomnia?
Insomnia is a powerful REST and GraphQL API client that competes with Postman in the API development space. Now owned by Kong, Insomnia focuses on simplicity and developer experience. The user agent appears when developers use Insomnia for API testing, debugging, and development. Known for its clean interface and powerful features, Insomnia is particularly popular among developers who prefer open-source tools. The tool supports advanced features like environment variables, code generation, and response visualization.
